IVILIJIAM A. DRYSDALE, OF PHILADELPHIA, PENNSYLVANIA.

MUSIC-BOX.

SPECIFICATION forming part of Letters Patent No. 728,449, dated May 19,1903.

Application filed February 18, 1898. Serial No 670,771. (No model.)

To @ZZ whom, it may concern:

Be it known that LWILLIAM A. DRYSDALE, of Philadelphia, in the State ofPennsylvania, have invented certain new and useful Improvements inMusic-Boxes, whereof the following is a specification, reference beinghad to the accompanying drawings.

My invention relates to machines wherein a pattern-disk is actuated toeiect a predetermined operation of the machine or a predeterminedsequence of sounds from soundproducing members thereof. The -class ofmechanism aforesaid is typified in the musicbox I have illustrated,which comprises fixed combs having vibratory sounding-tongues andmechanism to rotate a removable disk, the latter being provided withpattern perforations or projections upon its face so related to saidtongues as to effect the vibration thereof during the rotative traverseof the disk.

Music-boxes of the class illustrated as ordinarily constructed areadapted for the successive insertion and removal of single disks whichare temporarily maintained in proper relation with the rotary mechanismby a oentral clamp fixed upon the extremity ofv an arm overhanging thedisk, said arm being hinged at its outer extremity upon the frame of theinstrument and manually operated to effect the insertion and removal ofeach disk.

My present invention comprises means whereby7 a series or pack of disksmay be simultaneously placed in a machine which in operating willsuccessively feed the disks of said series upon the rotary mechanism androtate and discharge each disk in succession at predetermined intervalswithout further attendance of the operator.

My invention also comprehends controlling mechanism whereby the numberofrevolutions of each disk may be varied, being predetermined at thewill of the operator, conveniently by the set of an index. i

In the drawings, Figure 1 is a plan view of a machine convenientlyembodying my invention, the parts being in position to begin rotation ofthe pattern-disk. Fig. 2 is a side elevation of the machine in itscasing, the latter being shown in section for cle-arnese ofillustration. Fig. 3 is a plan View of the marig. t

chine removed from its casing. Fig. 6 is a rear elevation of themachine, certain parts being omitted for ol'earness of illustration.Fig. 7 is a plan sectional view of themachine,

showing the controlling mechanism by which' the number of revolutions ofeach patterndisk is predetermined. Fig. 8 is a vertical sectional viewon the axial line of the controller-dial. Fig. 9 is a plan view of thecontroller-dial. Fig. 10 is a sectional View showing the locking-plungerof the controller-dial. Fig. 1l is a sectional view taken on the line 1111 in Fig. 5 in the direction of t-he arrows upon said line. Fig. l2 isa sectional view taken on the line 12 12 of Fig. 1l in the direction ofthe arrows upon said line. Fig. 13 is a sectional detail view of themotor-shaft and parts connected therewith. Fig. 14 is a sectional detailview of the clutch worm-gear upon the extremity of the maindriving-shaft. Fig. 15 is a fragmentary sectional view takentransversely of Fig. 5 in the same direction as Fig. 11, showing thedetails of the clutchshifting mechanism with the parts in the positioninitial to the operation ofthe disk-transferring mechanism. Fig. 16 is adetail View showing the position of the parts of the tripping-cam whenautomatically set for operation. Fig. 17 shows the position of the partsof the trippingcam about to actuate the clutch-shifting mechanism tostop the disktransferring mechanism and start the diskrotatingmechanism. lar to that of Fig. 15, showing the position of the partsinitial tothe operation of the disk-rotating mechanism.

Fig. 36 is a sectional viewtaken on the line 36 36 in Fig. in the direction of the arrows upon saidline. Fig. 37 is a plan view of a typical form of disk peculiarlyadapted to cooperate with my improved mechanism. Figs. 38 and 39 aresectional views of supporting-bosses upon said disk, 'the former showingthe preferred form.

Referring to the drawings, AX is an inclosing casing which serves toconveniently support the bed-frame plate A and its depending frame A',the., upon and between which are mounted the ordinary elements ofthemusical instrument and the mechanism comprising a convenient embodimentof my invention.

The ordinary elements of the instrument aforesaid comprise fixed combsBX, the vibratory tongues 19X of which differ in length, the., inaccordance with the sound-pitch they are designed to produce. Each ofsaid tongues is provided with an idle spur-Wheel b', mounted forrotation in the bearingblocks B. Said spur-wheels b' project above saidbearingblocks to engage projections z upon the rotary pattern-disk Z.Said disk Z is rotated by its detachable engagement upon the shaft thelatter having a disk-driving head B2, provided with an eccentricdriving-pin b2, and a centralconepin b3. Said pins fit respectiveapertures z and .e2 in the disk Z, which thus centered and rotativelyengaged.

The pattern upon each disk Z being formed bythe projectionse' upon itslower surface existing at intervals in concentric circles in registrywith the respective idle spur-Wheel b', it is obvious that when saiddisk is rotated by its engagement, as aforesaid, said projections ,e'contact with the respective idle spurwheels bl and through the lattervibrate the respective tongues hX of the sounding-combs BX in a sequencepredetermined by the relative position of said projections a.

The shaft B may be rotated in the direction of the arrow upon l by anysuitable actuating mechanism. As ordinarily constructed, however, saidactuating mechanism comprises a spring-motor B3, (see Fig. 3,) thespring being adapted to be wound by means of the exterior handle l) uponthe shaft Z7, the latter connectingr with the spring-drum by thebevel-gears Said drum im parts its nnwinding motion of rotation to saidshaft B by the gears b5.

The embodiment of my invention which I have shown comprises a main shaftC, from which the various associated devices comprising my invention areactuated. A simple form of my invention would therefore consist of saiddevices connected with said shaft C and entirely separate from the motorwhich effects the rotation of the disk, but mounted upon the bed-plate Ain such relation with said ordinary elements of the instrument as tocoperate therewith to feed and discharge the disks. In such anembodiment of my invention the shaft C may be manually actuated at theproper intervals by means of the exterior handle c.

The dimensions of a motor of the spring type above described arenecessarily such as to limit the time of its unwinding operation to afew minutes, thus necessitating the frequent manipulation of thewinding-handle b. Therefore the preferred embodiment of my inventioncomprises a motor-shaft DX, provided with a band-wheel dX, exterior tothe casing AX, so that it may receive continuous rotary motion from someexterior source, such as an electric motor. In said preferred form of myinvention the parts are so related that the respective shafts B and Omay be alternately actuated from said motor-shaft DX by means of anantomatically-operative clutch mechanism, so that the continuous rotarymotion of the exterior band-wheel ZX through the shaft C, dac., effectthe transference of the disks Z at the proper intervals and through theshaft B, dac., effects the successive rotation of said disks at theproper intervals, the relation of said intervals of disk rotation anddisk transference being controlled, as aforesaid, by amanually-adjustable index H, hereinafter at length described. Said shaftDX extends through the casing AX and is provided with a clutch memberCZ, adapted for fixed engagement with the clutch member cl2 upon theshaft D when the mechanism is in its normal position within said casing.The two shafts being thus normally continuous are separable, asaforesaid, merely for convenience of removal of the mechanism from thecasing.

Referring to Figs. 11, 12, 13, and 14, the shaft D is mounted in thebearing a in the frame member A2, depending from the bedplate A, and isprovided with a couplingsleeve D2, keyed for endwise reciprocationthereon to alternately engage with the clutchhead d3 of thedisk-rotating mechanism and the clutch-head d4 of the disk-transferringmechanism. The head cl3 is fixed upon the shaft D3 and is shaped toreceive the extremity of the shaft D, which is supported for rotationtherein independently of said shaft D2, the latter being mounted forrotation in the bearings ct a in said frame member A2. The clutch (Z4 isloosely mounted upon the shaft D' and provided with a worm D4 in meshwith the worm-gear C' upon the shaft C. Said worm-gear C. is looselymounted upon the shaft C, butis adapted to rotate the latter in thedirection of the arrow upon Fig. 11 by the engagementof the ratchet cupon the gear with the pawl c2, pivoted upon the plate C2, fixed uponsaid shaft. Said ratchet permits the transferring mechanism to bemanually operated forwardly by the handle c. (See Fig. I prefer,however, to fix the gear C' upon the shaft C and make the latter in twoparts connected for actuation by the gear C', dac., through the frictionunion CX to permit the manual rotation of said mechanism in eitherdirection without disturbing the relation of said gear C with thedriving-worm D4, fixed upon the shaft D'. The worm D5 is fixed upon theshaft D2 and engages with the worm-gear D6, fixed uponv the shaft D'Said shaft D7 is mounted for rotation in the bearing @2in the framemember A2 and in the bearing d2 upon the frame member A. The worm Ds isfixed upon said shaft D7 in position to engage the worm-gear B4, fixedupon the shaft B. It is therefore obvious that when `the clutch-sleeveD2is engaged with the clutch-head cl2 the'rotary motion of the shafts DXDl is transmitted to said shaft B and through its driving-head B2 to thedisk Z, seated thereon.

As is usual in mechanism of this class, the speed of rotation of theshaft B may be governed within certain limits by the fan E, thegear-wheel B5 upon said shaft B being operatively connected with saidfan E through gears e', e', and e2, the latter being engaged with theworm e2 upon the arbor E' of the fan. The detent-arms EX are fixed uponthe fanarbor E' and serve to contact with the detentlever FX, by whichthe motion of said fan and its train aforesaid is arrested at the properintervals, as hereinafter described.

Before describing the detailed construction of the parts comprising thedisk-transferring mechanism operated by the main drivingshaft C, I shalldescribe the general arrangement and cooperative relationship of saidrespective parts, as follows: The standards I, existing in the fourcorners of the rectangular bed-plate A, conveniently support a series ofthe disks Z in readiness forsuccessive transference to the rotary headB2. Said standards have fixed heads IX, each provided with a pair ofmovable blades 'L' t', adapted, as hereinafter described, tosuccessively release each disk at the bottom of the series or pack whichrests upon said blades, the pack of disks being laterally supported bythe fixed guide-bars J JX. The disksZ mustbe maintained, as shown inFig. 1, with their apertures Z in registry with the driving-pin b2 uponthe driving-head B2, so that when released, as aforesaid, they willdescend in proper position with respect to said drivinghead and saidpin. I have therefore provided each of said disks with a singleperipheral notch a2, adapted to engage the guide JX, which'is set withinthe circumferential line bounded by the other guides J. Said disks aretherefore maintained in proper registry, and it is impossible tootherwise place them upon the standards I. When a disk Z is dropped uponthe driving-head B2, the clampshafts K, provided with the idle rollers7c, serve to retain said disk in proper position relative to thespur-wheels h', tbc. The diskbearingl rollers L serve to upwardlydeflect the disk Z, engaged upon the head B2 beneath the idle rollersle. The disk Z is thus stiffened for engagement with the spurwheels b'and prevented from chattering during its rotary movement.

During the operation of discharging the disk Z, as shown in Figs. 3 and4:, the rollers L are lowered, the disk being uplifted by thedischarging-rollers M, mounted for rotation in the frame M', saidrollers serving to deliver the disk upon the track-arms N N, which aremaintained parallel until said disk has IOO been fully discharged uponthem, being then diverged, as shown in Fig. 1, dropping the disk uponthe disk-rack aX, fixed upon the exterior' of the casing AX.

The main driving-shaft C of the disk-transferring mechanism is providedwith the bevelgear cX, in mesh with the bevel-gear gX upon the shaft GX,mounted for rotation in the frame. members A5 A6. The bevel-gear g uponthe opposite extremity of the shaftv GX is in mesh with the bevel-gearg', fixed upon the cam-shaft G. Said shaft G is mounted for rotation inthe frame members A3 A4 and is provided with cams to actuate therespective members of the disk-transferring mechanism, as follows: Ishall first describe the details of construction of the standards I andthe blades by which said disks Z are normally supported and successivelydropped upon the driving-head, referring particularly to Figs. 22 to 28.Each of the heads IX incloses diskreleasing blades fi t", adapted forreciprocation beneath the disks Z. Said blades t' t are separated intheir respective heads IX by the diaphragms t'X and are provided withoppositely-disposed notches t2 t2, respectively, for engagement with therespective crahkpins t t5 upon the crowns I fixed on the verticalrock-shafts I2. The latter extend through 'IIO
